Error when adding negative percentage reduction (fee)

[RabbitZzZ]

Hi,

I rund PS 1.6.1.9 (recently updated from 1.6.0.14).

When I want to add a negative percentage reduction (so to say a percentage fee) to an order from the backoffice, I get the following error thrown:

[PrestaShopException]

Property CartRule->reduction_percent is not valid
at line 909 in file classes/ObjectModel.php

904.             }
905. 
906.             $message = $this->validateField($field, $this->$field);
907.             if ($message !== true) {
908.                 if ($die) {
909.                     throw new PrestaShopException($message);
910.                 }
911.                 return $error_return ? $message : false;
912.             }
913.         }
914.

If it's a fixed amount (also negative) it works. Is there a way to fix this in the code?

Thanks a lot!

Now I also get the error message with fixed amounts! 

Please help, this is really bad!

Hi there,

 

sorry to tell you that what you would like to do is not possible with core PS code.

You will need a custom module for this (check out in the Addons, there are some).

 

Have a nice day,

Hm, ok, thanks! I thought it worked on previous versions... Can you recommend a module for this?

[fedesib]

Hi there,

 

I don't know about previous version, but I'm pretty sure it does not work on PS 1.6.

As for a module that does this, I can suggest this one:

 

http://addons.prestashop.com/en/12794-fees-and-reductions-shipping-surcharge.html

 

But I also suggest you to check if there is something that better fits your needs in the Addons.

 

I hope this helps, have a nice day,

Federica
